BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Antirrhinum, botanically known as Antirrhinum majus×Antirrhinum hispanicum and hereinafter referred to by the name ‘Sunkisupin’.

The new Antirrhinum is a product of a planned breeding program conducted by the Inventors in Shiga, Japan. The objective of the breeding program is to create new freely flowering potted Antirrhinums.

The new Antirrhinum originated from a cross-pollination in Shiga, Japan in May, 2002 of a proprietary selection of Antirrhinum majus×Antirrhinum hispanicum identified as code number His13-4, not patented, as the female, or seed, parent with a proprietary selection of Antirrhinum majus×Antirrhinum hispanicum identified as code number His13-2, not patented. The cultivar Sunkisupin was discovered and selected by the Inventors as a flowering plant from within the progeny of the stated cross-pollination in a controlled environment in Shiga, Japan.

Asexual reproduction of the new Antirrhinum by cuttings in a controlled environment in Shiga, Japan since November, 2005, has shown that the unique features of this new Antirrhinum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Sunkisupin has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sunkisupin’. These characteristics in combination distinguish ‘Sunkisupin’ as a new and distinct cultivar of Antirrhinum:

-   -   1. Upright and mounded plant habit.     -   2. Freely branching habit and short internodes; dense and bushy         plant form.     -   3. Numerous dark pink-colored flowers.     -   4. Long flowering period.

Plants of the new Antirrhinum differ from plants of the parent selections primarily in flower size as plants of the new Antirrhinum have larger flowers than plants of the parent selections.

Plants of the new Antirrhinum differ from plants of the cultivar Sunkisupapu, U.S. Plant Patent application filed concurrently, primarily in flower color.

Plants of the new Antirrhinum can be compared to plants of the cultivar Festa Pink, not patented. Plants of the new Antirrhinum and the cultivar Festa Pink differ in the following characteristics:

-   -   1. Plants of the new Antirrhinum are taller and broader than         plants of the cultivar Festa Pink.     -   2. Plants of the new Antirrhinum have longer and thicker lateral         branches than plants of the cultivar Festa Pink.     -   3. Plants of the new Antirrhinum are more freely branching than         plants of the cultivar Festa Pink.     -   4. Plants of the new Antirrhinum have smaller leaves than plants         of the cultivar Festa Pink.     -   5. Plants of the new Antirrhinum have much longer inflorescences         than plants of the cultivar Festa Pink.     -   6. Plants of the new Antirrhinum have lighter-colored flowers         than plants of the cultivar Festa Pink.     -   7. Plants of the new Antirrhinum are more freely flowering than         plants of the cultivar Festa Pink.
